A special court-martial began Thursday for an Air Force Academy cadet accused of using synthetic marijuana.

Kami Bohannon, a junior at the academy, faces charges of failure to obey an order or regulation and making false official statements in connection with an investgation into the use of “Spice,” a substance that mimics the effects of marijuana.

Prosecutors allege that she used “Spice” between May 1, 2011 and June 30, 2011, according to a charge sheet. She also is accused of lying to an investigator.

Thirty-one cadets were accused of using illegal substances during an investigation announced in January. At least 13 cadets were cleared, the academy said in June. Several were expelled, including Asher Clark, the second-leading rusher in academy football history.

Bohannon played 26 games for the academy’s women’s basketball team last season, starting two and averaging 2.5 points and two rebounds a game, according to the academy’s sports website.

Bohannon’s court-martial is expected to last through Saturday.
